# Send S3 to your agent Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually. ## Fast path - Download the package from Yavira. - Extract it into a folder your agent can access. - Paste one of the prompts below and point your agent at the extracted folder. ## Suggested prompts ### New install ```text I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete. ``` ### Upgrade existing ```text I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run. ``` ## Machine-readable fields ```json { "schemaVersion": "1.0", "item": { "slug": "s3", "name": "S3", "source": "tencent", "type": "skill", "category": "数据分析", "sourceUrl": "https://clawhub.ai/ivangdavila/s3", "canonicalUrl": "https://clawhub.ai/ivangdavila/s3", "targetPlatform": "OpenClaw" }, "install": { "downloadUrl": "/downloads/s3", "sourceDownloadUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=s3", "sourcePlatform": "tencent", "targetPlatform": "OpenClaw", "packageFormat": "ZIP package", "primaryDoc": "SKILL.md", "includedAssets": [ "SKILL.md" ], "downloadMode": "redirect", "sourceHealth": { "source": "tencent", "slug": "s3", "status": "healthy", "reason": "direct_download_ok", "recommendedAction": "download", "checkedAt": "2026-04-30T03:21:57.835Z", "expiresAt": "2026-05-07T03:21:57.835Z", "httpStatus": 200, "finalUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=s3", "contentType": "application/zip", "probeMethod": "head", "details": { "probeUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=s3", "contentDisposition": "attachment;

treat as secret Specify HTTP method in signature—GET for download, PUT for upload Include Content-Type for uploads—mismatch between signature and request causes 403 Generate server-side, never expose credentials to client ### Lifecycle Rules Transition to cheaper tiers for infrequent access—but check minimum storage duration penalties Auto-delete for temp files, logs, old versions—prevents unbounded storage growth Clean incomplete multipart uploads—accumulate invisibly; set abort rule (7 days typical) Versioned buckets: separate rules for current vs noncurrent versions ### Versioning Behavior Enable before you need it—can't recover deleted objects without versioning "Delete" creates delete marker—object hidden but versions remain; storage still consumed Permanent deletion requires explicit version ID—without it, just adds marker Noncurrent version expiration essential—otherwise old versions accumulate forever ### Multipart Uploads Required above 5GB, recommended above 100MB—single PUT has size limits Incomplete uploads invisible in normal listings—consume storage silently Abort incomplete uploads via lifecycle—or manually with list-multipart-uploads Parallel part uploads for speed—parts can upload concurrently ### CORS for Browser Access Required for JavaScript direct upload/download—blocked without CORS headers Specify exact origins—avoid wildcard * for authenticated requests Expose headers that JavaScript needs to read—Content-Length, ETag, custom headers AllowedMethods: GET for download, PUT for upload, DELETE if needed ### Key Naming Use prefixes like directories: users/123/avatar.jpg—but S3 is flat, not hierarchical Avoid sequential prefixes for high throughput—2024-01-01/file1 can hotspot Random prefix or hash for write-heavy buckets—distributes across partitions No leading slash—/images/file.jpg creates empty-string prefix ### Cost Awareness Request volume matters—many small files more expensive than few large files Egress typically costly—CDN reduces egress by caching at edge Minimum storage duration varies by tier—early deletion still charged full period Lifecycle transitions have per-object cost—millions of tiny files expensive to transition ### Replication Cross-region for disaster recovery, same-region for compliance copies Versioning required on both source and destination Only new objects replicate—existing objects need manual copy or batch operation Delete markers not replicated by default—explicitly enable if needed ### Provider Differences AWS S3: full feature set, most tools assume AWS behavior Cloudflare R2: no egress fees, subset of features Backblaze B2: S3-compatible API, different pricing model MinIO: self-hosted, full S3 API compatibility Check presigned URL compatibility—some providers have quirks ## Trust - Source: tencent - Verification: Indexed source record - Publisher: ivangdavila - Version: 1.0.0 ## Source health - Status: healthy - Item download looks usable. - Yavira can redirect you to the upstream package for this item. - Health scope: item - Reason: direct_download_ok - Checked at: 2026-04-30T03:21:57.835Z - Expires at: 2026-05-07T03:21:57.835Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/s3) - [Send to Agent page](https://openagent3.xyz/skills/s3/agent) - [JSON manifest](https://openagent3.xyz/skills/s3/agent.json) - [Markdown brief](https://openagent3.xyz/skills/s3/agent.md) - [Download page](https://openagent3.xyz/downloads/s3)
